<title>MOS Technology KIM-1 specific information for cc65
|
||||
<author><url url="mailto:davepl@davepl.com" name="Dave Plummer">
|
||||
|
||||
<abstract>
|
||||
An overview of the KIM-1 runtime system as it is implemented for the cc65 C compiler.
|
||||
</abstract>
|
||||
|
||||
<!-- Table of contents -->
|
||||

<!-- Begin the document -->
|
||||
|
||||
<sect>Overview<p>
|
||||
|
||||
This file contains an overview of the KIM-1 runtime system as it comes with the cc65 C compiler.
|
||||
It describes the memory layout, KIM-1 specific header files, available drivers, and any pitfalls
|
||||
specific to the platform.
|
||||
|
||||
Please note that KIM-1 specific functions are just mentioned here, they are described in detail
|
||||
in the separate <url url="funcref.html" name="function reference">. Even functions marked as
|
||||
"platform dependent" may be available on more than one platform. Please see the
|
||||
function reference for more information.
|
||||
|
||||
<sect>Binary format<p>
|
||||
|
||||
The output format generated by the linker for the KIM-1 target is a raw binary BIN file, which
|
||||
is essentially a memory image. You can convert this to a papertape format file using
|
||||
Convert8bithexformat or KIMPaper, which are open-source conversion utility programs.
|
||||
A papertape format files can be transferred to the KIM-1 using the RS-232 terminal port (TTY),
|
||||
just as if the machine-code was entered by hand. Enter 'L' in the TTY and start the paper tape file
|
||||
transfer.
|
||||
|
||||
<p>
|
||||
|
||||
Included with this distribution is a 4k configuration file and a 60k config file. The KIM-1
|
||||
on-board memory is limited to 4 kbytes but system memory can be increased to 60 kbytes of
|
||||
contiguous RAM with aftermarket add-on boards. So choose the config file that matches your
|
||||
system configuration before compiling and linking user programs.
|
||||
|
||||
<sect>Memory layout<p>
|
||||
|
||||
The ROMs and I/O areas are defined in the configuration files, as are most of the entry points
|
||||
for useful subroutines in the KIM-1 monitor ROM. cc65 generated programs compiled and linked
|
||||
using 4k config run in the memory range of $200 - $0FFF. The 60k config expands
|
||||
this range to $DFFF. The starting memory location and entry point for running the program is
|
||||
$200, so when the program is transferred to the KIM-1, it is executed by typing '200 G'.
|
||||
|
||||
Special locations:
|
||||
|
||||
<descrip>
|
||||
<tag/Text screen/
|
||||
Conio support is not currently available for the KIM-1. But stdio console functions are available.
|
||||
|
||||
<tag/Stack/
|
||||
The C runtime stack is located at $0FFF on 4kb KIM-1s, or at $DFFF for 60kb systems.
|
||||
The stack always grows downwards.
|
||||
|
||||
<tag/Heap/
|
||||
The C heap is located at the end of the program and grows towards the C runtime stack.
|
||||
|
||||
</descrip><p>
|
||||
|
||||
<sect>Platform specific header files<p>
|
||||
|
||||
Programs containing KIM-1 code may use the <tt/kim.h/ header file. See the header file for more information.
|
||||
|
||||
<sect>Loadable drivers<p>
|
||||
|
||||
<sect1>Graphics drivers<p>
|
||||
|
||||
No graphics drivers are currently available for the KIM-1.
|
||||
|
||||
<sect1>Joystick drivers<p>
|
||||
|
||||
No joystick driver is currently available for the KIM-1.
|
||||
|
||||
<sect1>Mouse drivers<p>
|
||||
|
||||
No mouse drivers are currently available for the KIM-1.
|
||||
|
||||
<sect1>RS232 device drivers<p>
|
||||
|
||||
No communication port drivers are currently available for the KIM-1. It has only the "master console"
|
||||
e.g. stdin and stdout.
|
||||
|
||||
<sect>Limitations<p>
|
||||
|
||||
<sect1>Disk I/O<p>
|
||||
|
||||
The existing library for the KIM-1 doesn't implement C file I/O.
|
||||
|
||||
To be more specific, this limitation means that you cannot use any of the following functions (and a few others):
|
||||
|
||||
<itemize>
|
||||
<item>fopen
|
||||
<item>fclose
|
||||
<item>fread
|
||||
<item>fwrite
|
||||
<item>...
|
||||
</itemize>
|
||||
|
||||
<sect>Other hints<p>
|
||||
|
||||
<sect1>kim1.h<p>
|
||||
This header exposes KIM-1 specific I/O functions that are useful for reading and writing its ports and front panel.
|
||||
See the <tt/kim1.h/ include file for a list of the functions available.
|
||||
|
||||
<sect1>Limited memory applications<p>
|
||||
|
||||
As stated earlier, there are config files for 4kb and 60kb systems. If you have 60kb RAM, then you will probably
|
||||
want to use the kim1-60k configuration, but if not - if you are using the kim1-4k configuration - then you may
|
||||
want to use functions like getchar, putchar, gets and puts rather than functions like scanf and printf.
|
||||
Printf, for example, requires about 1KB because it needs to know how to process all the format specifiers.
|
||||
|
||||
<sect1>Sample programs<p>
|
||||
|
||||
These sample programs can be found in the samples/kim1 directory:
|
||||
|
||||
<itemize>
|
||||
<item>kimHello prints "Hello World!" and then inputs characters, which are echoed on the screen.
|
||||
This program will run on both 4kb and 60kb systems.</item>
|
||||
<item>kimSieve finds the prime numbers up to 100,000 using the Sieve of Eratosthenes algorithm, and prints how many
|
||||
prime numbers were found. This program requires a 60kb system to run.</item>
|
||||
